Engine Options:
Typically powered by Case IH's own diesel engines, likely variants of the 3.1L or 3.9L 4-cylinder naturally aspirated or turbocharged engines (e.g., 4-239, 4-248, or later direct injection designs).
Horsepower Range:
Approximate horsepower ratings typically ranged from 60-85 HP depending on the specific engine variant and model designation (685 vs. 885).
Torque Specifications:
Torque figures would be specific to engine configuration and RPM, critical for tasks like PTO operation and heavy draft work.
Injection Type:
Likely a Bosch inline or rotary fuel injection pump system, possibly with indirect or direct injection depending on the specific engine variant and production year.
Cooling Type:
Liquid-cooled system with a radiator, fan, thermostat, and water pump.
Oil Capacity:
Typical engine oil capacity would be around 8-10 liters (8.5-10.5 quarts) with filter, but specific figures are crucial and found in the manual.
Air Cleaner Type:
Likely a dry-type paper element air filter, potentially with a pre-cleaner (e.g., centrifugal separator) for dusty conditions.
Gearbox Type:
Often featured a mechanical constant mesh gearbox offering multiple forward and reverse speeds (e.g., 8 forward, 4 reverse or similar configurations).
Powershift Option:
Some models may have offered a powershift transmission option (e.g., a 2-speed Hi-Lo splitter) for on-the-go gear changes.
Clutch Type:
Dual-clutch setup: one for PTO engagement and a main clutch for ground drive, or a single clutch for both functions depending on specification.
Transmission Oil Type:
Typically specified a UTF (Universal Tractor Transmission Oil) or a specialized gear oil, requiring precise viscosity and additive packages for hydraulics and gears.
Wheelbase:
Wheelbase varied by configuration but was generally around 2200-2300 mm (approx. 86-91 inches).
Operating Weight:
Operating weight typically ranged from 2500-3000 kg (approx. 5500-6600 lbs) depending on configuration and fitted options.
Front Axle Weight:
Crucial for stability and steering, detailed specifications for front axle load capacity would be present.
Rear Axle Weight:
Rear axle load capacity would be significantly higher, accommodating implement weight and traction needs.
Rollover Protection:
Many units would have featured optional or standard Roll Over Protective Structures (ROPS) and seat belts for operator safety.
Braking System:
Typically featured internal expanding shoe or disc brakes, often hydraulically operated, with independent or linked pedal functions.
Lighting:
Includes headlights, taillights, and potentially work lights for operation in low visibility conditions.
Radio Options:
Factory radio options were basic, typically AM/FM radios. Aftermarket upgrades are common.
Traction Control:
No advanced electronic driver assistance systems like traction control or ABS were standard on these models; reliance is on operator skill and mechanical systems.
Data Logging:
No electronic data logging or connectivity features beyond basic diagnostic points for engine management (if applicable to later EFI models).
Engine Oil Change:
Typically 250 hours or annually, whichever comes first. Specific interval and oil grade are critical and detailed in the manual.
Transmission Hydraulic Service:
Often recommended at 1000 or 1200 hours, including filter replacement. Critical for drivetrain longevity.
Air Filter Replacement:
Check and service based on operating conditions, replace as needed, typically annually or when restriction indicators activate.
Engine Oil Grade:
Typically API CG-4 or CH-4 rated diesel engine oil, viscosity grade often SAE 15W-40. The manual will specify the exact grade and quality.
Coolant Type:
A mixture of ethylene glycol antifreeze and water, typically a 50/50 mix for freeze protection and corrosion inhibition. Manual will specify type and concentration.
Common Wear Points:
Potential wear in transmission synchronizers, clutch components, hydraulic pump, and steering linkages due to age and usage.
Electrical Gremlins:
Older wiring harnesses can degrade, leading to intermittent electrical faults, particularly in lighting and instrument cluster circuits.
Hydraulic Leaks:
Seals in hydraulic cylinders, pumps, and hoses are susceptible to wear, leading to leaks and reduced hydraulic performance.
Manufacturer:
Case IH, a prominent American manufacturer of agricultural machinery, with a long history of innovation.
Series Context:
These tractors were part of Case IH's established line of utility and row-crop tractors, successors to earlier influential models.
Production Period:
The 685/885 series likely spanned production from the mid-1980s into the early 1990s, potentially with variations and upgrades during their run.
